Description

Tidal power plant

This creation belongs to the field of green energy, especially a tidal power generation device that is easy to erect, sturdy and durable, easy to maintain, and can generate electricity stably and efficiently.

With the progress of society and the improvement of the quality of life, human beings have an increasing demand for electricity, so more sources of electricity are needed to meet the constant demand.

In terms of traditional power energy, it mainly adopts thermal power generation, that is, burning oil and coal to directly and indirectly drive the generator to operate, and then obtain a certain power output. However, fossil fuels are highly polluting substances, which will produce amazing pollutants when they are burned, causing serious pollution to air and water sources, which is a great persecution to the environment. Although governments all over the world have also seen the problem, they have set strict standards for pollution levels, and cooperate with the introduction of new technologies, hoping to reduce the pollution of thermal power generation, but the effect that can be obtained is limited, and with more thermal power generation The construction of factories and the use of fossil fuels have had adverse effects on the earth's environment and ecology, and have affected the daily lives of many people.

Another problem is that fossil fuels are limited resources, and no matter how much their reserves are, they will be used up one day. In addition, oil is in the hands of a few countries, and most countries are putting their national defense, people's livelihood, and economy under the control of others. A little carelessness can easily lead to national turmoil. The seriousness of this is a national security issue.

For this reason, it is imperative to seek new energy alternatives. Most countries, both official and private, have recognized the urgency of the energy crisis and are actively investing in research and development, hoping to come up with effective alternatives as soon as possible.

Regarding the currently known energy alternatives, mainly include solar energy, wind energy and hydroelectric power. Among them, solar energy is the most well-known green energy. Although it meets the needs of environmental protection, the disadvantage is that the power generation efficiency is very low, and due to the weather, it cannot continuously supply energy. Another common green energy source is wind power generation, which is more efficient than solar energy, but has the disadvantage of not being able to supply wind power continuously and stably, and can only be applied in a few countries with strong wind power. Compared with the aforementioned solar energy and wind energy, hydropower should be a stable energy source with higher efficiency and easy control, but the water source area must be considered, and it is easy to cause serious damage to the landform and ecology around the power plant, and it is not perfect. solution.

To this end, many industry players have turned their attention to the ocean, hoping to provide human beings with clean and safe energy by covering seven-tenths of the earth's surface with ocean energy. At present, there are two main ways to obtain ocean energy: one is to generate electricity from ocean waves. The method is to install turbines on the sea surface, let the waves beat and rotate the turbines, and then the turbines are linked to the generator to generate electricity. However, ocean waves are not a stable natural phenomenon, not only unsustainable Provides effective energy, and because of the impact ability of the waves, the damage to the turbine is much greater than that of rotating power generation, making it difficult to implement wave power generation; another method is tidal power generation. Because the ocean has stable tides every day, its The energy generated is quite huge. However, the tidal power generation unit must be immersed in seawater, which is not only difficult to install, but also difficult to detect and maintain in the future. In addition to the erosion effect of seawater, the cost of tidal power generation has increased significantly. , and it is prone to failure and must be shut down for maintenance, making its stability sink, and it cannot form an effective alternative energy solution.

In view of this, although tidal power generation is an excellent green energy source, there are still insurmountable problems in the existing technology, making it difficult to effectively promote the application of tidal power generation.

The surface of the guide post 200 is provided with a spiral channel 210 .

The movable platform 300 is sleeved around the four positioning rods 110 and can be moved up and down by sea water. The movable platform 300 has a rotating shaft 130 in the middle. The upper and lower ends of the rotating shaft 130 are respectively provided with rotating bearings on the inner sides of the movable platform 300 140 , so that the two ends of the rotating shaft 130 abut against the rotating bearing 140 to freely rotate relative to the movable platform 300 . The rotating shaft 130 is hollow inside and is sleeved on the guide post 200 , and a plurality of guide bearings 150 are arranged inside the rotating shaft 130 , so that the plurality of guide bearings 150 can be in contact with the helical channel 210 to allow the movement of the rotating shaft 130 .
